Product Description
Non-Magnetic Tungsten Carbide Inner & Outer Ring Set
Engineered Together for Flawless, Interference-Free Assembly
Precision assembly demands components engineered to work in perfect harmony. Our Non-Magnetic Tungsten Carbide Inner & Outer Ring Set provides a complete, ready-to-install solution for applications where absolute magnetic neutrality, micron-level concentricity, and guaranteed fit are non-negotiable. Fabricated as a matched pair from the same batch of WC-Ni alloy, these rings eliminate assembly guesswork and performance risks in MRI, semiconductor, and high-vacuum systems.
Material & Key Specifications
Base Material: WC-Ni (Tungsten Carbide - Nickel) Alloy
This proprietary formulation replaces ferromagnetic cobalt with nickel, achieving true non-magnetic properties without sacrificing the legendary hardness of tungsten carbide.
| Property | Specification | Benefit |
|---|---|---|
| Magnetic Permeability (µ) | < 1.002 | Zero magnetic attraction or interference, safe for the most sensitive environments (MRI, labs) |
| Hardness | 90 - 92 HRA | Exceptional resistance to wear, abrasion, and deformation for long-term dimensional stability |
| Density | ~14.9 g/cm³ | Provides excellent rigidity and vibration damping characteristics |
| Corrosion Resistance | Excellent | Withstands exposure to coolants, certain chemicals, and cleanroom processing agents |
Standard Set Configuration & Tolerances
Each set consists of one precision-ground inner ring and one outer ring, engineered to fit together seamlessly.
Typical Standard Set (Fully Customizable):
| Component | Inner Diameter (ID) | Outer Diameter (OD) | Height / Width | Critical Tolerance |
|---|---|---|---|---|
| Inner Ring | e.g., Ø20.000 mm | e.g., Ø30.000 mm | e.g., 10.00 mm | ID: H6 (±0.004mm) |
| Outer Ring | e.g., Ø30.020 mm (Matched Fit) | e.g., Ø40.000 mm | e.g., 10.00 mm | OD: h6 (±0.004mm) |
Key Machining Capabilities for the Set
- Concentricity (Between ID & OD): ≤ 0.003 mm
- Parallelism (End Faces): ≤ 0.003 mm
- Surface Finish: Ra 0.2 - 0.4 μm (standard), mirror polish (Ra < 0.1 μm) available
- Fit Tolerance: Clearance or transition fits (e.g., H6/g6, H6/h6) are standard; other fits can be manufactured to order
Applications
This matched set is ideal for building the foundation of high-precision, non-magnetic assemblies.
| Industry | Typical Use Case |
|---|---|
| Medical & MRI | Shimming assemblies, gradient coil mounts, and RF shield components where non-magnetic properties and precise spacing are critical for image quality |
| Semiconductor | Wafer stage modules, precision bearing housings, and vacuum chamber fixtures requiring stable, non-contaminating, and non-magnetic structural rings |
| Aerospace & Defense | Guidance system housings, inertial sensor mounts, and optical platform isolators that demand zero magnetic signature and high dimensional stability |
| Advanced Research | Cryostat assemblies, particle detector components, and laser optics mounts in experimental physics and materials science labs |
